I'm in the USA and my cloud node still downloads the same files each time, so per Umberto's pinned post, use the offline installer. I try to use it once a day just to be safe until he tells everyone the Live Updater is working for everyone.
If you used the offline installer, then went to LiveUpdater and updated again, it will potentially download "old" files from the live servers, so you'll need to go back to offline installer again.
